CATO supplies 6-Chloro-2-((4-(trifluoromethyl)phenyl)amino)-4H-benzo[d][1,3]oxazin-4-one (CAS 477859-08-8), a certified reference material (molecular formula C15H8ClF3N2O2, MW 340.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 6-Chloro-2-((4-(trifluoromethyl)phenyl)amino)-4H-benzo[d][1,3]oxazin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Chloro-2-((4-(trifluoromethyl)phenyl)amino)-4H-benzo[d][1,3]oxazin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
